# Changelog

All notable changes to Daybook are recorded here. Format loosely follows
[Keep a Changelog](https://keepachangelog.com/); versions are SemVer and match
the git tags (`vX.Y.Z`) and `daybook_project.__version__`.

## [Unreleased]

### Added
- `GET /api/skill` serves the bundled agent-posting skill as Markdown (or
  `?format=json`), with `DAYBOOK_URL` pre-filled to the instance's own
  origin so the instructions are ready to hand to an AI. Advertised as
  `skill_url` in `/api/capabilities`.

### Changed
- Rewrote the posting skill (`skills/daybook-posting/SKILL.md`) to be
  location-agnostic: no longer assumes a local source checkout, reframes
  `DAYBOOK_URL` as set-your-instance, and adds a raw `curl` fallback.

## [0.1.0] — 2026-09-03

First tagged release.

### Artifacts & rendering
- Artifact kinds: `markdown`, `html_fragment`, `html_full`, `deck`, `json`,
  `csv`, `image`, `pdf`, `binary`.
- `.xlsx` uploads convert server-side to a `csv` artifact (active sheet,
  saved formula results).
- Markdown code blocks get syntax highlighting; tables (markdown &
  html_fragment) render styled — monospace cells, sans-serif headers.
- `json`/`csv` render as an interactive collapsible tree / sortable table
  (Grid.js + renderjson, vendored locally).
- Unified off-white document background; system sans-serif body text.

### API
- `POST/GET/PATCH/DELETE /api/artifacts`, list filters (source/label/day/
  kind/q), `/api/assets` image upload, `/api/capabilities` (reports
  `version`). Per-user bearer-token ingest; session-authed reads.
- Server-side validation: per-kind content shape, field length limits,
  string-typed source fields, valid-JSON for `json`.

### Sharing, quotas, security
- Per-artifact public share links (`/s/{token}`), owner-toggled, revocable.
- Per-user disk quotas with oldest-unkept auto-eviction and a Keep flag.
- Allowlist HTML sanitization (nh3) + `script-src 'none'` CSP for the themed
  kinds; deep-JSON parse errors return 400 (not 500).

### UI
- Multi-user auth; feed with source sidebar + label filtering; settings area
  (Account, Storage, Demo Data, Users, About); light/dark toggle; app icon.

### Deployment
- Dockerised (Gunicorn + whitenoise), SQLite, `git`-based deploy with a
  runbook (`deploy/cloud_agent_deploy.md`) and health check.
